检查下面的查询。大多数情况下，它应该在你的情况下工作。它可能不会立即执行，请根据您的要求进行修改

SELECT id, LISTAGG (unit || ' ' || unit_description, ', ') WITHIN GROUP (ORDER BY unit, unit_description) FROM ( SELECT id, unit_description, SUM (unit) AS unit FROM table1 GROUP BY id, unit_description) GROUP BY id;

到目前为止你做了什么？你可以从小组学习开始。

id  | unit details
12 70 KWh , 100 days
15 80 KWh

SELECT id, LISTAGG (unit || ' ' || unit_description, ', ') WITHIN GROUP (ORDER BY unit, unit_description) FROM ( SELECT id, unit_description, SUM (unit) AS unit FROM table1 GROUP BY id, unit_description) GROUP BY id;
